If Rahul does take top honours he’ll become the first male winner of the competition since John Whaite took the title in 2012.

The winners since then have been Frances Quinn in 2013, Nancy Birtwhistle in 2014, Nadiya Hussain in 2015, Candice Browbn in 2016 and Sophie Faldo in last year’s debut series on Channel 4.

The Great British Bake Off final kicks off on Channel 4 on Tuesday night at 8pm.
